Abstract

We review some aspects of spin physics where QCD instantons play an important role. In particular, their large contributions in semi-inclusive deep-inelastic scattering and polarized proton on proton scattering. We also review their possible contribution in the P-odd pion azimuthal charge correlations in peripheral AA scattering at collider energies.
